First Experimental Result of Power Analysis Attacks on a FPGA Implementation of LEA
نویسندگان
چکیده
The lightweight encryption algorithm (LEA) is a 128-bit block cipher introduced in 2013. It is based on Addition, rotation, XOR operations for 32-bit words. Because of its structure, it is useful for several devices to achieve a high speed of encryption and low-power consumption. However, side-channel attacks on LEA implementations have not been examined. In this study, we perform a power analysis attack on LEA. We implemented LEA with 128-bit key size on FPGA in a straightforward manner. Our experimental results show that we can successfully retrieve a 128-bit master key by attacking a first round encryption.

Differential Power Analysis: A Serious Threat to FPGA Security
Differential Power Analysis (DPA) implies measuring the supply current of a cipher-circuit in an attempt to uncover part of a cipher key. Cryptographic security gets compromised if the current waveforms obtained correlate with those from a hypothetical power model of the circuit. As FPGAs are becoming integral parts of embedded systems and increasingly popular for cryptographic applications and...
متن کاملThreshold Implementation as a Countermeasure against Power Analysis Attacks
One of the usual ways to find sensitive data or secret parameters of cryptographic devices is to use their physical leakages. Power analysis is one of the attacks which lay in such a model. In comparison with other types of side-channels, power analysis is so efficient and has a high success rate. So it is important to provide a countermeasure against it. Different types of countermeasures use ...

Authenticated encryption schemes are important cryptographic primitives that received extensive attention recently. They can provide both confidentiality and authenticity services, simultaneously. Correlation power analysis (CPA) can be a thread for authenticated ciphers, similar to the any physical implementation of any other cryptographic scheme. In this paper, a three-step CPA attack against...

Nowadays there are different kinds of attacks on Field Programmable Gate Array (FPGA). As FPGAs are used in many different applications, its security becomes an important concern, especially in Internet of Things (IoT) applications. Hardware Trojan Horse (HTH) insertion is one of the major security threats that can be implemented in unused space of the FPGA. This unused space is unavoidable to ...
متن کاملPower-Analysis Attacks on an FPGA - First Experimental Results
Field Programmable Gate Arrays (FPGAs) are becoming increasingly popular, especially for rapid prototyping. For implementations of cryptographic algorithms, not only the speed and the size of the circuit are important, but also their security against implementation attacks such as side-channel attacks. Power-analysis attacks are typical examples of side-channel attacks, that have been demonstra...
